Abstract: An object of the present invention is to provide an EL display device, which has a high operating performance and reliability.A third passivation film 45 is disposed under an EL element 203 which comprises a pixel electrode (anode) 46, an EL layer 47 and a cathode 48, to make a structure in which heat generated by the EL element 203 is radiated. Further, the third passivation film 45 prevents alkali metals within the EL element 203 from diffusing into the TFTs side, and prevents moisture and oxygen of the TFTs side from penetrating into the EL element 203. More preferably, heat radiating effect is given to a fourth passivation film 50 to make the EL element 203 to be enclosed by heat radiating layers.

Abstract: Failure light emission of an EL element due to failure film formation of an organic EL material in an electrode hole 46 is improved. By forming the organic EL material after embedding an insulator in an electrode hole 46 on a pixel electrode and forming a protective portion 41b, failure film formation in the electrode hole 46 can be prevented. This can prevent concentration of electric current due to a short circuit between a cathode and an anode of the EL element, and can prevent failure light emission of an EL layer.
